- 論文の詳細を見る
Motivated by recent magnetic anisotropy measurements, we performed neutron scattering experiments for a single crystal of a typical geometrical frustration system (ZnCr_2O_4) under a magnetic field. The magnetic structure of ZnCr_2O_4 is easily affected by the applied magnetic field of about 2T. The (hh0) (h=n/2, n=odd) series magnetic Bragg peaks disappear when the magnetic field is applied along the [111] axis. It means that the magnetic structure turns into a new structure with higher symmetry than that in the ground state under a small magnetic field.
